Bacterial effectors are injected by bacterial cells, usually pathogens, into the cells of their host. The injection is mediated by specialized secretion systems, e.g. the type III secretion system (TTSS or T3SS).ungal effectors are secreted by pathogenic fungi into and around host cells by invasive hyphae to disable defense components and facilitate colonization.
